We might want a simple "summary matrix" for the major versions showing which features exists in which version, and link to the correct ones. That way you can see the differences between versions and can go to the appropriate doc pages as well.

Ideally users could find all info needed to use a feature on a single page. The versioned pages, such as http://doc.akka.io/docs/akka/2.1.2/scala/dataflow.html might satisfy this with minor additions:

1. Include on each versioned page a link to where the needed (jar or other) resources may be downloaded
2. Describe any required setup, like sbt build or classpath changes
3. Make the "version" field a popup that links to the other versioned pages.

Motivation comes from new users attempting to run (obsolete) example code, which then breaks. The example, which is meant to provide an easy on-ramp to using a feature, instead becomes a source of frustration. This ticket appears to derive from this thread:
